Engaged molding
The delicate balance between the flat top edge and the hollow below it on this gabled molding ornamented only with punched bands acknowlege the fine draftsmanship of the "Exaltation of Saint Nicholas of Tolentino" by Giovanni di Paolo (ca. 1400-1482). The decorative palm fronds that cross above Nicholas's head and the fluttering scroll held by Saint Augustine serve to divide the composition. The panel was never part of a larger structure.
